open-multi-agent/examples/with-vercel-ai-sdk

with-vercel-ai-sdk

A Next.js demo showing open-multi-agent (OMA) and Vercel AI SDK working together:

• OMA orchestrates a research team (researcher agent + writer agent) via runTeam()
• AI SDK streams the result to a chat UI via useChat + streamText

How it works

User message
  │
  ▼
API route (app/api/chat/route.ts)
  │
  ├─ Phase 1: OMA runTeam()
  │    coordinator decomposes goal → researcher gathers info → writer drafts article
  │
  └─ Phase 2: AI SDK streamText()
       streams the team's output to the browser
  │
  ▼
Chat UI (app/page.tsx) — useChat hook renders streamed response

Setup

# 1. From repo root, install OMA dependencies
cd ../..
npm install

# 2. Back to this example
cd examples/with-vercel-ai-sdk
npm install

# 3. Set your API key
export ANTHROPIC_API_KEY=sk-ant-...

# 4. Run
npm run dev

npm run dev automatically builds OMA before starting Next.js (via the predev script).

Open http://localhost:3000, type a topic, and watch the research team work.

Prerequisites

• Node.js >= 18
• ANTHROPIC_API_KEY environment variable (used by both OMA and AI SDK)
